C) Gallery feature

Additionally you get the opportunity to handle all products in just one product list:

• products with inventory status available (gallery, shop available)
• products with inventory status reserved or soldout (gallery, shop not available)
• products with inventory status not for sale (gallery, shop not available)

Configuration

Your settings can be individual per product-type and per product. In backend's shop-configuration you can activate the attributes you want to use for a given product-type:

inventory_status	not for sale	set by backend user if applicable
	available	default
	reserved	system set
	soldout	system set
quantity	number of items available for sale	set by backend user, modified by system
minQuantityPerOrder	minimum number of product items allowed for an order	set by backend user
maxQuantityPerOrder	maximum number of product items allowed for an order	set by backend user

All attributes can be changed by a backend user.

Configuring just the gallery feature (without HandleLimitedEditions)

You may activate only inventory_status. Then only the options not for sale and available are used and there will not be any further stock-management for this product-type. Use this, if you just want to want to combine shop and gallery.

Configuring limited editions

If you have limited editions, activate quantity to enable stock-management for this product-type. Then you MUST activate inventory_status, too. (Othwerwise an exception will be thrown).

For products with no limit keep the quantity field empty. Then there will be no stock-management for this product.

Recommended additional configuration for limited editions

You may want to receive a notification when a product is overbought (this can happen if there are concurring updates simultaneously, e.g. another order by another user). Then you need to do this as well:

Add a notification of type change order status. Under shop configuration add an order status Overbought (mind the exact spelling!) and link this notification to it.

Configuring limited orders

If you want to limit the quantity per order, activate minQuantityPerOrder and/or maxQuantityPerOrder for this product-type. Make sure to set the maximum equal to or greater than the minimum! (Othwerwise an exception will be thrown).

For products with no such limit keep the respective field(s) empty.
